Here are some tools found in using Ubuntu Linux.
The diff program is used to find differences between files. To know more about diff : http://www.google.com/search?hl=fr&q=man+diff
But, if we use diff in svn folder, it can find a difference between files inside .svn. Here is the line of code I’m using :
cd /where/is/my/svn/folder
diff -r -x .svn /folder/source /folder/dest > file
With these parameters, diff doesn’t look into .svn folder.
One day I had some troubles with my computer. Sometimes it crashes both spontaneously and sporadically. I thought it was because the CPU’s temperature was to hight. So here is a command line to know more about the CPU’s temperature on linux (I’m using Ubuntu 9.10)
cat /proc/acpi/thermal_zone/*/*
But this line shows me that the temperature of my CPU was completely normal. I think that my computer has some power problems, but impossible to discover the cause of crashes. Fortunately, it seems to work now…
Sometimes, you need to make a pause in your Linux script. For instance, you want to see the result of your script when you’re executing it from the window system. In my case, when I want to open an executable script file from gnome, it asks me if I want to open it in a new bash. If I say yes, it executes it and close the window. I don’t have the time to see any output, so I’m writing this at the end :
read a
The system wait for a keyboard input. The input is finish after pressing the « enter » key. Pressing it, the window closes itself (when executing from the window system)
I have found on the web a useful command to delete .svn folders in your local svn repository. I found it here.
The command line is as follow :
find ./ -name .svn -exec rm -rf {} \;
The command find will search in the ./ directory each element whose -name is .svn. Don’t forget to go into your svn directory with the cd command. After each successful research, the -exec command will execute rm -rf with the path found by find put into the {} brackets. The result is that each .svn folder found is deleted.
